And what's going to happen is absolutely unpredictable.
That's exactly why we talk about probabilities 
Some hands are just in some situations much more likely than others, but that is of course no guarantee that the cards are actually drawn so. Otherwise, probably no one would play the lottery, even there it is purely from the probability almost impossible that you win. Poker is certainly one of the games in a casino that depends least on luck, closely followed by other card games such as blackjack.
I agree
But predicting cards in poker is much easier than predicting numbers in lottery that is going to make you rich. 52 cards in a deck in poker game that only has 2,598,960 total combinations while there is a 1 in a 13,983,816 chances you could win the jackpot in lottery in a classic 6/49 game. But for an average gambler, surely they won't do math while playing poker because they don't have much time for that unless they are practicing at home so that they could execute it easily in an actual game.
